Benchmark of toy calculation on an n-dimensional array using python, numba, cython, pythran and rust - ndarray_comparison/comparison.ipynb at main · synapticarbors/ndarray_comparison

A little while ago there was a post on /r/rust describing huge gains in porting some numerical code from python to rust. The gains were impressive, but as someone who has worked with python for a long time, I know it’s pretty easy to write really slow python. There are a number of options within the ecosystem to get more performant code, and how effective the strategy is highly depends on the nature of the bottleneck.
